Seems to be rather common with certain ASUS board.
Read through http://www.google.com/search?hl=en&q=%22overclocking+failed%22+&btnG=Google+Search to see if anything ringa a bell or applies.
About 5 days ago I logged on and my pc went bananas. Had to completely shut off power, then power on and log on again. More strange activity and a message "Overclocking Failed", use options F1 or F2. Did so and all went fine for about 3 minutes, then same thing occured again. Shut off all power then powered on and logged on. This time received message to key on the highlighted "Start Windows Normally". This time all went well for the rest of the time online
BUT this same thing happens each time I boot and log on. I sure didn't engage in attempting to overclock and don't know what else I could have done. Haven't messed with anything except to check/verify fan operation and connections. Have also noticed that programs are exceedingly slow to open (examples: Spyware Doctor, Ad-Aware, AVG, even accessing my Yahoo browser.
I run Windows XP Home - SP2. MB is ASUS P4B with P4 at 3.0GHz.
Appreciate suggestions as to how to correct this anomoly.
